First Neumotor
 

I got it and noticed that it doesn't spin freely like the other cheap motors. Why is that? It turns a lot harder, you can really feel the magnets when you turn it.

torque from the 4 poles...

have you installed it in your truck yet?

once you do you will see why.

these things are amazing.

Mine was like that, but once installed it is sweeeet!

I think it's mostly to do with it having a slotted stator.

^ +1. Motors with slotted stators have a greater magnetic attraction since the magentic field is being concentrated via a metal core. But, since the field is concentrated, the rotor range where this attraction is strongest is smaller.

I could have explained it like that if I wanted to. :wink:

Of course, I just thought I would expand on your initial statement... :smile:

Is this a Neu 1500? My Neu 1900 also cogs heavily and have been curious to know if the 1500s are the same.

I think my Hacker C40 is the only free spinning motor that I've seen before...

I haven't had any cogging with my 1515 1y.

I have not ran it yet, waiting for my esc to get repaired, I blew both my quark and MGM :(. I think my quark will get here next week.

How have you blown your MGM:gasp:

4 other guys at racing have been running MGM's, 3 of them have burnt out MGM's.

My emaxx is too heavy, 12 lbs. I run 5S in the sand, and race. One day it stopped, the issue was that the motor was cooked. I didn't know this, and kept trying things with the ESC. Once I figured out it was the motor, I put a new one on, 10xl. That one ran great, until it started to smoke one day, and when I put the temp gun on it, it was 300 degrees.

I put an 8xl in, but ran a low gear, and set my radio EPA to 65%. That setup ran fine for a while. While I was running in the sand racing it stopped. From that point on, the ESC would not turn any motor. To test that, I got a motor that another ESC could turn, but the MGM would not, and no beeping. So I'm not sure if it was my killing the motors or what.

OK, i came to the conclusion that they don't have any real good ESC:neutral:
We can pay $300.00 or $500.00 for an ESC and that's not a proof that the ESC will be better than a cheap $100.00 one.
My friend have run a brushless LST2 with a Nemesis Blue and a MM on 4s, all summer long, without any trouble...... And the LST2 is way heavier than the Maxx or revo!!!

I think that the first thing everyone notices when they go to the neu from a feigao. I remember thinking the same thing when I tried to spin the neu for the first time.

I don't mean cogging with power. I mean free spinning, with no current flowing through the motor...

if it was a two pole motor, it would spin freely....

My new Ammo motor (35-50-2300kv) turns mich tighter than my old cc36-5700kv motor. I'm pretty sure it's the "dual sealed" bearings. I've ran it a few times now and it's starting to free up a bit, would imagine the lower kv windings would have less magnetic drag? or am I thinking about it wrong? or do the windings not have any effect on magnetic drag, just the magnets themselves?

Using the Neu, pletty, novak design, it will still turn rough. That is the design of the slotted (or caged, as i called it before knowing it was called slotted). Its the web the windings are wound on that make it rough to turn.
